Resolving the problem
Workaround
Ensure all Controller users out of the system. Reboot Controller application server.

Long-term Fix:
Optimise the Cognos 8 BI reporting service environment, by:
Ensure that Controller product is upgraded to latest release, to take advantage of memory leak fixes, such as those described inside IBM Technotes #1347915, 1367340 & 1365078.
Afterwards, if the problem persists, follow the advice inside separate IBM Technote articles #1341779, 1021723 & 1032429.
